3 is a sectional view through the center 9;

. the binding clamp and screw.

Similar letters refer to similar parts throughout the several views.

A is that port-ion of the tool by which it is secured, when in use and is made in such proportions that it will fit the ordinary tool 'post. Between the head of the tool and the shank is the slot M, partially dividing the headfrom the shank' 'forming the spring G so that when under an undue strain the blade D has a tendency to spring away from the cut, the bottom of the blade is given a bearing the entire length of the head 0, and on a part of the shank A, at P.

The blade D is secured by the binding clamp F, held in position by the binding screw G, the lower part of the blade rests on the longitudinal projection E and with the bottom of the cutting blade forms a pivot, for the blade adjustment. The'topof the blade is held in a shallow groove I, in the blade clamp, transversely to'this grooveis a tongue K, arranged to slide in a slot in the tool head. A 'slot hole H in the binding clamp allows a movement to the top of the cutting blade, so that the clearance on either side of the blade may be equally divided, an essential feature in a tool of this class. When it is desired to give the cutting blade the proper alinement the binding screw G is loosened and the binding clamp is moved till the proper alinement is obtained, not only is the proper alinement given to the blade, but the projection of the cutting blade.

ing through said slot, and having a screw threaded engagement with said head.

In witness whereof, I have hereunto afiixed my signature in the presence of two witnesses.
